According to the invention, during a sound recording or playback operation, the recording medium 18 is is held stationary. Therefore, the periphery of the recording medium is transparent at the bottom of the frame 14. It is securely held below the bright cover 15. Frame 14 is hung by button 94. It is released from the stopped state (latched state) and rotated together with the cover 15. Lifting allows removal and replacement of the recording medium.

Returning to FIG. 2 again, the hardware section enclosed in the housing 12 The unit exhibits a single start-up function during playback operation and records an audible signal during recording operation. It has a recording/playback signal head 32 that exhibits the t@ function. The second head 34 erases Both of these signal heads, which have the function An actuating sub-arrangement relationship is established with respect to the magnetic signal recording surface 20 of the material sheet constituting the recording medium 18. The zero positioning carriages 36 and 38, which are kept in It is movably mounted on the upper gear wheel member 40 of the conversion drive mechanism.

Drive mechanism 42 according to one embodiment includes a common fixed rotation extending through bearing shaft portion 46. The lower gear wheel rotates relative to the upper gear wheel member about the axis of rotation. It has a member 44. The number of teeth on the annular outer gear of both gear wheel members is small. The teeth of the gear wheel member 44 are reliably repositioned to provide a common drive. They are meshed with a moving pinion 48 and driven simultaneously at different speeds. The drive pinion 48 , is connected to the electric drive motor 60 via a speed/direction selection mechanism 96 as shown in FIG. It is connected to a gear 50 meshing with a pinion 52 connected thereto. gear wheel The member 40 is raised or lowered by the motor 60 via the drive unit 42 and the selection mechanism 96. Driven by speed ratio. In one particular embodiment, gear wheel members 40 and 44 are provided with 170 and 168 teeth, respectively, and therefore the speed difference corresponding to the above number of teeth is As a result, when the device is activated in response to the start-up of the motor 60, The difference in relative rotational speed (of the roll members) is small.

As shown more clearly in Figures 3, 4, 5 and 6, the signal head position Positioning carriages 36 and 38 are slidably mounted on gear wheel member 40; By providing the dovetail guide portions 62 and 64 180 degrees apart from each other in the cross section, Rotates together with the gear wheel member. Each positioning platform has a pair of coil springs 66. is connected to the gear wheel and urges the platform radially inward. 40, thus acting as a signal iS current conductor to the signal head, and thus below the gear wheel 40. The cam driven roll 68 is connected to the carriage at the lower gear wheel 44. The pair of helical cam elements 70 are held in contact with and stopped together with the elements 70. Since the speeds of the two rotating gear wheels are different, that is, the relative rotational motion is different, the motor During the continuous rotation of both gear wheels by the motor 60, each carriage is rotated in half by the cam element 70. deflected radially outward and returned to a radially inward position by the bias of spring 66 When the cam follower roll 68 returns to the radially inner position at the end of the 0 actuation cycle, , operates switch 98 to cut off power from the switch and stop the motor.

The motor can then be restarted by operating the start button switch 30. Ru. Thus, in each operating cycle, both signal heads 32 and 34 are placed in a spiral path. Above static along! a It becomes possible to make a relative displacement with respect to the medium 18.

The linear velocity of each signal head while moving along the spiral path is determined by the angular velocity and half the rotation axis. Since it is a function of radial distance, in order to perform appropriate signal recording and playback operation, In order to maintain both signal heads at a constant linear velocity, the rotational speed of the motor can be changed. A rheostat 72, such as a carbon film type or the like, is adjacent to the erase head 34. It is also mounted on the gear wheel 40 along the guide portion 64 for positioning operation. It is controlled by the radial movement of the platform 38. Therefore, the resistance value of resistor 72 is The radial distance of the linear velocity above varies in response to the radial component along the helical path of the This cancels out the effect of changes in , and a constant linear velocity is obtained. The resistor 72 is shown in FIGS. 2 and 5. As shown, it is electrically connected to the governor circuit 54 by a conductor via a connector device 74. conductors from signal heads 32 and 34 are also recorded by connector device 74. It is electrically connected to the sound/reproduction circuit 76.

Continuing to explain with reference to FIG. 7, as shown in the figure, the speed regulating circuit is connected to a connector device 74. is connected to the motor 60 and power source 78 in series with the rheostat 72 through the output A well-known method that varies the speed and keeps the signal head along the spiral path at a constant linear speed. Any type of selection device 96 can be connected between the motor 60 and the power source to Select the magnitude of constant linear velocity under the control of switches 84, 86 and 88, and Change the direction of rotation of the head. According to a particular embodiment, switch 84 is selected to Both signal heads are set at a low constant linear speed of 1.6cn/sec and the size is 8 inches x 11 inches. It is also possible to record speech signals for 16 minutes on a recording medium of 4.8cn/s. You can also record music for 5 minutes at a constant linear velocity.

Fig. 8 shows a modified embodiment having a modified drive mechanism of 42 degrees. The lower gear 44 of the mechanism 42 is replaced with a helical cam mounted thereon. ing. Only the upper gear 4o is rotated by the pinion 48', as shown in Figs. As with the mechanism 42 described above with reference to FIGS. 3 and 5, the gear 40 The signal head carriages 36' and 38', which are slidably mounted on the signal head carriages 36' and 38', are rotated. death While the carriages 36° and 38° are below the gear 40, The nut 100 is connected to a pair of screw nuts 1oo, and the nut 100 is connected to a pair of radially extending leads. It is threaded through the screw 1°2. The radially inner end of the lead screw has small diameter bevel teeth. It is connected to a composite planetary bevel gear assembly having a wheel 104 and a large diameter bevel gear 110.

A fixed shaft 46' on which the gear 4o rotates has a non-rotating sleeve 112 in a key groove. Therefore, it is attached. A pair of reaction bevel gears 106 and 110 are axially are fixed to the sleeve 112 at a distance of The lower end of the sleeve 112, which meshes with the planetary bevel gears 104 and 108, a control lever 114 having a pair of starting arms 120 and 122 with different angular positions; is engaged with one arm 118 of. The lever 114 rotates at an angle about the fixed axis. It is arranged to be displaced and move into two operating positions which are held elastically by springs 116. It is attached.

When control lever 114 is in the position shown in FIG. The reaction bevel gear 106 is held in mesh with the planetary bevel gear 108. Therefore, an umbrella The gear 108 is connected to the carriage 36' and 38° by the gear 40 and the lead screw 102. When rotated about axis 46°, bevel gear 108 extends through the lead screw. Rotates around its own axis. Therefore, the lead screw is rotated by the bevel gear 108. The nut 100 is rotated at a relatively low speed to move the nut 100 radially outward along the lead screw. axially move in the direction.

Therefore, when the nut 100 is rotated by the gear 40, the carriages 36° and 38° is displaced radially outward to guide the signal head along a spiral path during recording or playback operation. move it.

When the screw nut 100 reaches its radially outer extreme position, the control lever 114 is released. arm 122 to displace the control lever clockwise as seen in FIG. 18 displaces the sleeve upwardly to move it to the upper position. Sleeve 112 is in the upper position, the bevel gear 110 meshes with the small diameter planetary bevel gear 104, Bevel gears 106 and 108 are separated. Therefore, the lead screw moves in the opposite direction at high speed. Rotate to move the nut 100 radially inward from the extreme radially outer position. . Accordingly, the carriages 36° and 38' move in the radial direction at high speed when the gear 40 rotates. Displace inward to quickly move the signal head.
